Thank you for viewing. This is a decorative item featuring a cute hippopotamus three-dimensionally floating inside a round crystal glass (or glass) sphere, created using 3D laser engraving. The silhouette of the hippopotamus is intricately engraved inside with a laser, and the expression and shape of the hippopotamus appear to change three-dimensionally depending on the viewing angle. This product is approximately 37mm (3.7cm) in diameter, making it a small size, perfect as a stylish paperweight on your desk or a mini object to display in a small space. It sparkles beautifully when light is shone on it. The material is crystal glass (or glass). Recommended for those who love hippos and those looking for unique interior decorations. There are no noticeable scratches or stains, but please understand that this is a used item before purchasing. The color may differ slightly from the actual product due to the shooting environment. Shipping will be carefully packed with cushioning material and sent via Mercari delivery. If you have any questions, please feel free to comment.
